We examine the spillover effects between sovereigns and banks in a model with a heterogeneous banking system. An increase in sovereign’s default risk affects financial intermediaries through two channels in this model. First, banks’ funding costs might increase, inducing higher interest rates on loans and bonds and a cut back in these assets. Second, financial regulator’s risk-weighted asset framework would assign higher weights to lower quality assets, implying a portfolio rebalancing and more deleveraging. While capital adequacy requirements weaken the impact of shocks emerging from the real economy, they amplify the effect of shocks on banks’ balance sheets.

This paper reviews empirical and theoretical work on the links between banks and their governments (the bank-sovereign nexus). How significant is this nexus? What do we know about it? To what extent is it a source of concern? What is the role of policy intervention? The paper concludes with a review of recent policy proposals.

Foreign holdings of emerging markets (EMs) government bonds have increased substantially over the last decade. While foreign participation in local-currency sovereign bond markets provides an additional source of financing and reduces sovereign yields, it raises concerns about increased sensitivity of yields to shifts in market sentiment. The analysis in this paper suggests that foreign participation and an undiversified investor base transmit global financial shocks to local-currency sovereign bond markets by increasing yield volatility and, beyond a certain threshold, amplify these spillovers. These estimates are robust to a range of econometric techniques including panel smooth threshold regression.

This paper examines the spillover effects of sovereign rating news on European financial markets during the period 2007-2010. Our main finding is that sovereign rating downgrades have statistically and economically significant spillover effects both across countries and financial markets. The sign and magnitude of the spillover effects depend both on the type of announcements, the source country experiencing the downgrade and the rating agency from which the announcements originates. However, we also find evidence that downgrades to near speculative grade ratings for relatively large economies such as Greece have a systematic spillover effects across Euro zone countries. Rating-based triggers used in banking regulation, CDS contracts, and investment mandates may help explain these results.

This paper provides a comprehensive survey of pertinent issues on sovereign debt restructurings, based on a newly constructed database. This is the first complete dataset of sovereign restructuring cases, covering the six decades from 1950–2010; it includes 186 debt exchanges with foreign banks and bondholders, and 447 bilateral debt agreements with the Paris Club. We present new stylized facts on the outcome and process of debt restructurings, including on the size of haircuts, creditor participation, and legal aspects. In addition, the paper summarizes the relevant empirical literature, analyzes recent restructuring episodes, and discusses ongoing debates on crisis resolution mechanisms, credit default swaps, and the role of collective action clauses.

A cutting-edge graduate-level textbook on the macroeconomics of international trade Combining theoretical models and data in ways unimaginable just a few years ago, open economy macroeconomics has experienced enormous growth over the past several decades. This rigorous and self-contained textbook brings graduate students, scholars, and policymakers to the research frontier and provides the tools and context necessary for new research and policy proposals. Martín Uribe and Stephanie Schmitt-Grohé factor in the discipline's latest developments, including major theoretical advances in incorporating financial and nominal frictions into microfounded dynamic models of the open economy, the availability of macro- and microdata for emerging and developed countries, and a revolution in the tools available to simulate and estimate dynamic stochastic models. The authors begin with a canonical general equilibrium model of an open economy and then build levels of complexity through the coverage of important topics such as international business-cycle analysis, financial frictions as drivers and transmitters of business cycles and global crises, sovereign default, pecuniary externalities, involuntary unemployment, optimal macroprudential policy, and the role of nominal rigidities in shaping optimal exchange-rate policy. Based on courses taught at several universities, Open Economy Macroeconomics is an essential resource for students, researchers, and practitioners. Detailed exploration of international business-cycle analysis Coverage of financial frictions as drivers and transmitters of business cycles and global crises Extensive investigation of nominal rigidities and their role in shaping optimal exchange-rate policy Other topics include fixed exchange-rate regimes, involuntary unemployment, optimal macroprudential policy, and sovereign default and debt sustainability Chapters include exercises and replication codes
